Instantiating a module that contains a function (exported) with a v128
in its signature is fine, but then later calling it will trap.
So v128 values are technically not callable from JS, but we can give it
a default argument of 0, and will later trap anyway. This is useful when
fuzzers generate functions with v128 in the signature of the main
function that we then later try to call.
